Answer:

It is convenient to divide the photosynthetic process in plants into four stages, each occurring in a defined area of the chloroplast: (1) absorption of light, (2) electron transport leading to the reduction of NADP+ to NADPH, (3) generation of ATP, and (4) conversion of CO2 into carbohydrates (carbon fixation).

Which statement best summarizes Newton's law of action-reaction? *

Tom [10]

Answer:

The correct answer is the third

Force equals mass times acceleration

Explanation:

Newton's second law says that force equals mass times the acceleration of the body

F = m a

This is the most used way to solve problems

The correct answer is the third

Newton's third law states that forces always work in pairs, by action and reaction

Newton's first law states that an object per macerate with constant speed unless some force modifies this state.

A watermelon is blown into three pieces by a large firecracker. Two pieces of equal mass m fly away perpendicular to one another

laiz [17]

Answer

given,

watermelon blown into three pieces

two pieces of mass m

both pieces speed = v = 31 m/s

mass of third piece = 3 m

using conservation of mass

$0 = m V \hat{i} + m V \hat{j} + (3\ m)V_3$

$V_3 = \dfrac{V}{3}(-\hat{i}-\hat{j})$

$V_3 = \dfrac{V}{3}\sqrt{1^2+1^2}$

$V_3 = \dfrac{V}{3}\sqrt{2}$

velocity of third component

$V_3 = \dfrac{31}{3}\sqrt{2}$

$V_3 = 14.61\ m/s$

angle

$\theta = tan^{-1}(\dfrac{-1}{-1})$

$\theta = tan^{-1}(1)$

$\theta = 45^0$

A swimmer does 3560 j of work in 55 s what is the swimmers power output?

ankoles [38]

Explanation:

Here it is given 

Work (W) = 3560 J

Time (t) = 55 sec

power (P) = ?

We know we have the formula 

 $p = \frac{w}{t}$ 

P = 3560/55

P = 64.73 watt

Which is not a property of light

Anestetic [448]

a) light is a form of matter less dense than air
b) light travels in straight lines
c) light has different colors
d) light has different intensities and can be dim or bright

Yes, thank you for coming back and supplying the list of choices.

At the level of Physics all the way up to somewhere in college, choice-a)
is not a property of light.

A beam is said to be statically determinate if all of its unknown reaction components can be determined by the static equilibriu

BlackZzzverrR [31]

Answer:

The correct option is propped cantilever beam.

Explanation:

A propped cantilever beam along with all the reactions is shown in the attached figure.

Since we can see that the number of unknowns are 4 but the equations of statics are only 3 thus we conclude that the beam is indeterminate to 1 degree.

For all the other beams the reactions and the equations are 3 each thus making the system determinate.
